Hardware Verification with RFID-Stored Build Information

ABSTRACT

In embodiments of hardware verification with RFID-stored build information, a mobile device includes hardware components and a radio-frequency identification (RFID) tag to store build information for hardware verification of the hardware components in the mobile device. A bootloader can interrogate the RFID tag to obtain the build information and compare the build information to current information of the hardware components in the mobile device. The bootloader can then determine whether the current information matches the build information. If the current information does not match the build information, then a message can be displayed on the mobile device indicating that unauthorized hardware is installed in the mobile device.

BACKGROUND

Portable devices, such as mobile phones, tablet devices, communication devices, and other types of computing and electronic devices are ever-increasing in availability and in different configurations of features and hardware. Some of these type devices, such as mobile phones, are starting to be available as a user-configurable consumer product, both before and after purchase. For example, a user may select specific hardware components to configure a mobile phone, such as specifying display size, camera resolution, battery capacity, processor speed, and/or memory size. However, designing a mobile device for configurability opens up the possibility of users changing the hardware configuration and components after purchase, and causing potential damage.

Further, a user may replace original equipment hardware components with inferior components of smaller capacity, lower resolution, slower speed, etc., and then look to have a mobile phone replaced or swapped for a newer one that has the better components, which are comparable to the original device hardware configuration and components. This can have a direct impact on warranty and service costs for a manufacturer of the device. Further, particularly challenging is selectable memory that can be easily unplugged and swapped-out for a lower-capacity memory. More importantly, changing out the memory can replace or eliminate the entire boot image and hardware configuration setup information for a mobile device.

DETAILED DESCRIPTION

Embodiments of hardware verification with RFID-stored build information are described, such as for any type of mobile device that may be available as a user-configurable consumer product. For example, a user can purchase a mobile phone and select specific hardware components to configure the device for purchase, such as by specifying display size, camera resolution, battery capacity, processor speed, and/or memory size. When the selected hardware components are installed and the device is assembled, the manufacturer can encrypt the international mobile station equipment identity (IMEI) of the device with the hardware specific configuration parameters, and store encrypted build information in the memory of a radio-frequency identification (RFID) tag included in the device.

The stored build information can then be obtained at a service center when a technician later services and/or upgrades the device. The original equipment hardware configuration of the device can be verified by comparing the current hardware configuration information to the stored, encrypted build information, and determining whether one or more of the hardware components have been changed or swapped-out. For example, a mobile phone can include a bootloader application that is initiated when the device is powered-up, and queries the RFID tag to obtain, decrypt, and compare the encrypted build information against the current hardware configuration information. If the build information matches the current hardware configuration information, then the mobile phone can continue to boot-up for normal operation. However, if the build information does not match the current hardware configuration information, the mobile phone may be started for operation with limited functionality, such as only being able to initiate an outgoing phone call.

In aspects of hardware verification with RFID-stored build information, a mobile device can include hardware components and a radio-frequency identification (RFID) tag to store build information for hardware verification of the hardware components in the mobile device. A bootloader can interrogate the RFID tag to obtain the build information and compare the build information to current information of the hardware components in the mobile device. The bootloader can then determine whether the current information matches the build information. If the current information does not match the build information, then a message can be displayed on the mobile device indicating that unauthorized hardware is installed in the mobile device. Further, an operating system of the mobile device can be loaded for restricted functionality in the mobile device, as well as one or more of the hardware components having limited functionality. Alternatively, if the build information does match the current information of the hardware components in the mobile device, then the operating system can be loaded for unrestricted functionality in the mobile device.

While features and concepts of hardware verification with RFID-stored build information can be implemented in any number of different devices, systems, environments, and/or configurations, embodiments of hardware verification with RFID-stored build information are described in the context of the following example devices, systems, and methods.

FIG. 1 illustrates an example mobile device 100 in which embodiments of hardware verification with RFID-stored build information can be implemented. The example mobile device 100 may be any type of mobile phone, tablet device, digital camera, or other types of computing and electronic devices. The mobile device 100 can be implemented with various components, such as a processing system 102 (e.g., one or more processors), a memory 104, an integrated display device 106, and any number and combination of various components as further described with reference to the example device shown in FIG. 4. Although not shown, the mobile device 100 can also include a power source, such as a battery, to power the various device components. Further, the mobile device 100 can include the different wireless radio systems, such as for Wi-Fi, Bluetooth™, Mobile Broadband, LTE, Near Field Communication (NFC), or any other wireless communication system or format for communication via respective wireless networks.

Generally, any one or more of the various components of the mobile device are collectively the hardware components 108 of the mobile device (e.g., to include the processor, memory, integrated display device, a camera device, and/or other hardware specific configurations). As noted above, a user may order and purchase a mobile device (e.g., a mobile phone) with a specific hardware configuration of components, such as with additional memory, a faster processor, a better camera, a specific display size, battery capacity, etc. When the mobile device 100 is assembled and the specific hardware configuration of components are installed in the device, build information 110 corresponding to the hardware configuration of the components can be stored, or encrypted and stored, in the device for later access and hardware verification. In embodiments, the build information 110 can be encrypted using the hardware configuration of the mobile device 100 and an international mobile station equipment identity (IMEI) prior to storing the build information.

In this example, the mobile device 100 includes a radio-frequency identification (RFID) tag 112 that has a RFID tag memory 114 implemented to store the build information 110, as well as other identifying data and/or information associated with the mobile device 100. Alternatively, any suitable non-volatile memory (e.g., the device memory 104) can be used to store the identifying data and/or information that is associated with the mobile device 100 separate from the RFID tag 112. Generally, RFID tags are small electronic tags or labels that can be programmed with the build information, identifying data, and/or other information associated with the mobile device 100. In this example, the build information includes a vendor identifier (ID) 116 and/or a model ID 118 for each of the hardware components 108 installed during manufacture and assembly of the mobile device. The vendor ID 116 associated with a hardware component 108 identifies the a manufacturer of the particular hardware component, and the model ID associated with the hardware component 108 can include any identifying information, such as a particular model number, product name, serial number, memory size, display resolution, and the like as it pertains to each respective hardware component 108.

Although only the one RFID tag 112 is shown and described as being implemented in the mobile device 100, each of the hardware components 108 (e.g., to include the processor, memory, integrated display device, a camera device, and/or other hardware components) may include an individual RFID tag that stores configuration and build information for the respective hardware component. Generally, the RFID tags (e.g., the RFID tag 112) are small electronic tags or labels that can be programmed with identifying data or other information (e.g., the build information 110). A RFID tag can include an ASIC/CPU module, as well as a communication bus for communicating with the processing system 102. In response to receipt of an interrogation signal, the ASIC/CPU module of the RFID tag formulates a response that may include the stored information from the RFID tag.

In implementations, a mobile device may also include a RFID reader 120 (also referred to as a RFID interrogator) that is implemented for two-way wireless communication 122 with radio-frequency identification (RFID) tags, such as the RFID tag 112 that is activated in the presence of the RFID reader 120 when interrogated for sensor data, such as the build information 110 and/or other device identifying data. The RFID reader 120 can transmit an interrogation signal as a broadcast message requesting RFID tags that are in range to return the identifying data or information that the RFID tags have stored. The RIFD tags can then wirelessly communicate the data information to the RFID reader via a radio frequency (RF) communication channel. Additionally, an RFID reader 124 that is external to the mobile device can be utilized for two-way wireless communication 126 with the RFID tag 112. The external RFID reader 124 can be utilized to program the build information 110 into the mobile device 100, such as when the device is manufactured, and the downloaded build information is maintained by the RFID tag memory 114 in the RFID tag 112.

In this example, the processing system 102 includes an operating system 128 and a bootloader 130 (also referred to as a bootloader application) that is implemented to initialize a power-on or startup process of the mobile device 100. The bootloader 130 can be implemented as a software application or module, such as computer-executable software instructions that are executable with a processor (e.g., with the processing system 102) to implement embodiments of hardware verification with RFID-stored build information as described herein. As software applications, the operating system 128 and the bootloader 130 can be stored on computer-readable storage memory (e.g., the device memory 104), such as any suitable memory device or electronic data storage implemented in the mobile device.

In implementations, the bootloader 130 can include the RFID reader 120 as an integrated component to obtain the build information 110 from the RFID tag memory 114 of the RFID tag 112. Alternatively, the RFID tag 112 can communicate the build information 110 to the bootloader 130 of the processing system 102 via a communication bus 132, such as any form of an I2C, SPI, UART, or other type of communication bus. When the mobile device 100 is powered-on, the bootloader 130 is implemented to execute before the operating system 128 or other software modules. The bootloader 130 can communicate with and interrogate the RFID tag 112 (e.g., via the RFID reader 120 or the communication bus 132) to obtain the build information 110 for hardware verification of the hardware components 108 in the mobile device. If the build information 110 was encrypted prior to being stored in the RFID tag memory 114 of the RFID tag 112, then the bootloader 130 can decrypt the build information when retrieved from the RFID tag memory. Alternatively or in addition, access to the RFID tag memory 114 can be passcode protected, and the bootloader 130 provides a passcode to gain access to the RFID tag memory when retrieving the build information.

Additionally, the bootloader 130 can query each of the hardware components 108 to obtain current information 134 for each of the respective hardware components via the communication bus 132. Generally, the current information 134 includes the same type of hardware component configuration information as the build information 110, such as a vendor ID and/or a model ID of each hardware component, to include any type of identifying information, such as a particular model number, product name, serial number, memory size, display resolution, and the like as it pertains to each respective hardware component 108.

In embodiments, the bootloader 130 can compare the build information 110 with the current information 134 for each of the respective hardware components 108, and based on whether the current information matches the build information, execute different instructions based on the comparison result. For example, the bootloader 130 can determine that the current information 134 of a hardware component 108 does match the build information 110 for the hardware component, and initiate loading the operating system 128 for unrestricted functionality in the mobile device 100.

Alternatively, the bootloader 130 can determine that the current information 134 of a hardware component 108 does not match the build information 110 for the hardware component, and initiate displaying a message 132 on the display device 106 indicating that the current information and build information associated with the particular hardware component do not match (e.g., indicating unauthorized, non-verified hardware is installed in the device). The bootloader 130 can then replace the build information 110 in the RFID tag memory 114 of the RFID tag 112 with the current information 134 that does not match the build information of the hardware components. Additionally, the bootloader 130 can then load the operating system 128 with limited or restricted functionality in the mobile device.

For example, when the current information 134 and the build information 110 do not match, the operating system 128 can be executed with limited functionality and the hardware component that does not match the build information can be disabled or restricted. In implementations, the operating system may still function to allow a user making a phone call with the mobile device, but limit other communication features of the device. In other instances, the mobile device 100 may be manufactured with a hardware component that can be limited based on the build information. For example, the device memory 104 may be installed in the mobile device 100 as a 128 GB memory, but then limited to a smaller size (e.g., 16 GB) when the operating system 128 operates with limited functionality.

Example methods 200 and 300 are described with reference to respective FIGS. 2 and 3 in accordance with implementations of hardware verification with RFID-stored build information. Generally, any services, components, modules, methods, and/or operations described herein can be implemented using software, firmware, hardware (e.g., fixed logic circuitry), manual processing, or any combination thereof Some operations of the example methods may be described in the general context of executable instructions stored on computer-readable storage memory that is local and/or remote to a computer processing system, and implementations can include software applications, programs, functions, and the like. Alternatively or in addition, any of the functionality described herein can be performed, at least in part, by one or more hardware logic components, such as, and without limitation, Field-programmable Gate Arrays (FPGAs), Application-specific Integrated Circuits (ASICs), Application-specific Standard Products (ASSPs), System-on-a-chip systems (SoCs), Complex Programmable Logic Devices (CPLDs), and the like.

FIG. 2 illustrates example method(s) 200 of hardware verification with RFID-stored build information. The order in which the method is described is not intended to be construed as a limitation, and any number or combination of the described method operations can be performed in any order to perform a method, or an alternate method.

At 202, hardware components are installed and a mobile device is assembled. For example, during manufacture of the mobile device 100, the RFID tag 112, the processing system 102, the memory 104, the display device 106, and other various components (e.g., collectively, the hardware components 108) of the hardware configuration are installed, and the mobile device 100 is assembled.

At 204, build information corresponding to the installed hardware components is generated. For example, the build information 110 that is stored in the RFID tag memory 114 of the RFID tag 112 is generated based on the hardware components that are installed in the mobile device 100 during manufacture and assembly. The mobile device 100 can be attached to a test fixture after the assembly and manufacture process, and the test fixture is implemented to generate build information. Alternatively, the mobile device 100 can be booted into a test mode or manufacture mode after assembly, and the build information 110 is generated and stored in the RFID tag memory 114 of the RFID tag 112 in the mobile device 100. The test mode or manufacture mode can be a specific setting, such as setting an I/O line on the processing system 102 to a particular state to indicate that the bootloader 130 should not be executed during the test or manufacture modes. Under normal operating conditions (i.e., user operation), the bootloader 130 (also referred to as the bootloader application) is executed before the operating system 128 or other software module.

At 206, the build information is encrypted and, at 208, the build information is stored in memory of a radio-frequency identification (RFID) tag. For example, the bootloader 130 encrypts the build information 110 that has been generated, and communicates with the RFID tag 112 in the mobile device 100 to store the build information 110 in the RFID tag memory 114. Alternatively, a test fixture or device generates and encrypts the build information 110 after manufacture of the mobile device 100, and communicates with the RFID tag 112 to store the generated build information in the RFID tag memory 114. For example, the external RFID reader 124 communicates 126 with the RFID tag 112 and can be utilized to program the build information 110 into the mobile device 100, and the downloaded build information is maintained by the RFID tag memory 114 in the RFID tag.

FIG. 3 illustrates example method(s) 300 of hardware verification with RFID-stored build information. The order in which the method is described is not intended to be construed as a limitation, and any number or combination of the described method operations can be performed in any order to perform a method, or an alternate method.

At 302, a bootloader application is executed in a mobile device. For example, the bootloader 130 (also referred to as the bootloader application) in the mobile device 100 is executed by the processing system 102 when the mobile device is powered-up for use.

At 304, a radio-frequency identification (RFID) tag in the mobile device is interrogated to obtain build information for hardware verification of hardware components in the mobile device. For example, the bootloader 130 interrogates the RFID tag 112 to obtain the build information 110 that is stored in the RFID tag memory 114. The build information 110 corresponds to when the hardware components 108 are installed during manufacture and assembly of the mobile device, and the build information includes the vendor identifier (ID) 116 and/or the model ID 118 for each of the respective hardware components. In implementations, access to the RFID tag memory 114 can be passcode protected and the bootloader 130 provides the passcode during interrogation of the RFID tag 112 to gain access to the RFID tag memory 114. Alternatively or in addition, the build information 110 can be encrypted prior to the build information being stored in the RFID tag memory 114, as described with reference to FIG. 2. Accordingly, the bootloader 130 can then decrypt the build information 110 subsequent to obtaining the build information from the RFID tag 112.

At 306, current information for each of the hardware components in the mobile device is identified. For example, the bootloader 130 that is implemented in the mobile device 100 identifies the current information 134 (e.g., a vendor ID and/or a model ID) for each of the respective hardware components 108 that are installed in the mobile device 100. Identifying the current information can include the bootloader 130 obtaining the current hardware configuration information from each of the hardware components 108.

At 308, a determination is made as to whether the current information matches the stored build information. For example, the bootloader 130 that is implemented in the mobile device 100 determines whether the current information 134 for each of the hardware components 108 matches the build information 110 for each of the respective hardware components. In implementations, the bootloader 130 compares the vendor identifier (ID) and/or model ID of the build information 110 to the vendor identifier (ID) and/or model ID of the current information 134 for each of the hardware components 108 to determine whether the hardware components are the ones installed during manufacture of the device.

If the build information and the current information match (i.e., “Yes” from 308), then at 310, an operating system is loaded for unrestricted functionality in the mobile device. For example, the bootloader 130 determines that the build information 110 and the current information 134 for the respective hardware components 108 match, and the bootloader initiates loading the operating system 128 for unrestricted functionality in the mobile device 100.

If the build information and the current information do not match (i.e., “No” from 308), then at 312, a message is displayed to indicate to a user that at least one of the hardware components does not match the build information (i.e., to indicate that an unauthorized hardware component is installed). For example, the bootloader 130 determines that the build information 110 and the current information 134 for a respective hardware component does not match, and the bootloader 130 initiates displaying a message on the integrated display device 106, indicating that at least one unauthorized hardware component 108 is installed in the mobile device 100.

At 314, the current information that does not match the build information is stored in memory of the RFID tag. For example, the bootloader 130 replaces the build information 110 in the RFID tag memory 114 of the RFID tag 112 with the current information 134 that does not match the build information of the hardware components. At 316, the operating system is loaded for restricted functionality in the mobile device. For example, the bootloader 130 initiates loading the operating system 128 with limited or restricted functionality in the mobile device 100.

FIG. 4 illustrates various components of an example device 400 in which embodiments of hardware verification with RFID-stored build information can be implemented. The example device 400 can be implemented as any of the computing devices described with reference to the previous FIGS. 1-3, such as any type of client device, mobile phone, tablet, computing, communication, entertainment, gaming, media playback, and/or other type of device.

The computer-readable storage memory 412 provides data storage mechanisms to store the device data 404, other types of information and/or data, and various device applications 414 (e.g., software applications). For example, an operating system 416 can be maintained as software instructions with a memory device and executed by the processing system 408. The device applications may also include a device manager, such as any form of a control application, software application, signal-processing and control module, code that is native to a particular device, a hardware abstraction layer for a particular device, and so on.
